Hello, Hovis,, I have the older type of Kojack, the Hydraulic scissor jack type, which I think was used for the Twin axle type, and came with an outer and inner supports. My Present Coachman , single axle, came with White Kojack jacking points ready fitted, but only on the outside. The new type of supports are much safer than the much older ones that could fold over very easily. Maybe some one ( DD ) has got a photo of the old type.
